VVILBUR A. (JOKE, OF NORFOLK, VIRGINIA, ASSIGNOR OF ONE-HALF TO CHARLESM. BARNETT, OF NORFOLK, VIRGINIA,

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters PatentNo. 783,929, dated February28, 1905.

Application filed May 28, 1904. Serial No. 21037 To all whom, it mayconcern: I

Be it known that I, WILBUR A. COKE, a citizen of the United States,residing at Norfolk, in the county of Norfolk and State of Virginia,

5 have invented new and usefulImprovements in Bottle-Stoppers, of whichthe following is a specification.

This invention relates to bott1estoppers,the object of the inventionbeing to provide a sim- IO ple device of this character which can beinexpensively produced and which is adapted for insertion into the neckof a bottle and which is of such construction that when in workingrelation it effectually precludes the fraudulent In other words, whenthe stopper is introduced into the neck of a bottle the latter is of thekind known as non-refillable.

In the drawings accompanying and forming a part of this specification 1have illustrated one simple adaptation of the invention, theconstruction of which will be fully set forth in the followingdescription. I do not limit myself, however, to the disclosure thusmade,

for certain changes in such structure may be adopted within the scope ofmy claims succeeding said description.

Referring to the drawings, Figure 1 is a longitudinal sectionalelevation of the upper part of a bottle provided with a stopperinvolving my invention. Fig. 2 is a perspective detail of the uppersection of the stopper, and Fig. 3 is a similar view of the lowersection thereof.

Like characters refer to like parts throughout the several figures.

The stopper illustrated may be made from any suitable inaterial forexample, glass or porcelain-and it is represented as consisting 4 of twoparts, (denoted generally by 5 and 6, re-

spectively,) the part 5 constituting what might be an upper one, whilethe part 6 constitutes a lower part, both of them being shown as oftubular or sleeve form. The two parts when assembled as represented inFig. 1 are adapted to be snugly and permanently fitted within the neckof a bottle, and for maintaining the permanent relation between theparts 1 pro Vide some suitable cement, as will hereinafter moreparticularly appear. 5

Each of the parts 5 and 6, as has been stated, is of tubular or sleeveform, and l will now specifically describe the structure of the part 6.

The sleeve or tube 6 is exteriorly rabbeted, cut away or reduced fromits top toward its bottom in order to present along said bottom anexternal annular shoulder or flange 7. The upper edge of said sleeve 6is represented as having diametrically opposite apertures, as 8,constituting ducts for the passage of liquid to be poured from thebottle 9. The bore of the tube or sleeve 6 is reduced, the reducedportion being concaved to present a seat for the valve 10, which isshown as being of sphericalv form and of the gravity type-that is tosay, 5 it automatically falls against its seat surrounding the port 11in the bottom of the tube or sleeve 6.

The internal diameter of the sleeve 5, as will be seen upon aninspection of Fig. i, is equal to the external diameter of the reducedportion of the sleeve 6, whereby such reduced portion can be fittedwithin the sleeve 5 in order to assemble the two parts, at which timethe upper apertured edge of the sleeve 6 will abut against the underface of the crown or top of the sleeve 5. The upper portion of the saidsleeve 5 is externally rabbeted or reduced, so that when the stopper isintroduced into the bottle there will be present between 30 the upperportion of the two-part plug and the neck an annular channel 12 for thepassage of the liquid from out of the bottle. The rabbeted portion ofthe sleeve or tube 5 is represented as having (:liainetrically opposite8 5 ports or perforations 13 opening into the interior of said sleeveand into the rabbeted portion.

When the two parts 5 and 6 are in assembled relationthat is, when thereduced portion of the part 6 fits within the part o the apertures 8will be in registration with the ports or perforations 13 to provide forthe flow of liquid through the tube '7, apertures 8, ports 9, and intothat part of the neck of the bottle above the plug when said bottle istilted to carry the valve 10 away from its seat. The crown or closed topof the sleeve or tube 5 is provided with diametrically oppositeprojections, as 14, constituting guards and shown as of segmental or fanform and l located directly over the perforations or ports 13. The outersurfaces of these guards or segmental projections 14: are adapted toengage or substantially engage the inner surface of the neck of thebottle, whereby said projections or guards prevent effectually thepassing of wire or a like article into the perforations 13, as in case awire could be passed through the perforations the valve 10 might beunseated to permit the fraudulent refilling of the bottle.

in introducing the stopper into the bottle I initially coat theexternally-reduced portion of the sleeve 6 with a quantity of suitablecement. 1 then slip the said reduced portion into the sleeve 5 and thenput both parts into the bottle-neck, so that they can drop toward theplace they are to finally occupy. *hen the under part 6 finds a lodgmentin the neck, I press the upper part 5 downward until the lower edgethereof is contiguous to the upper edge of the annular shoulder 7. Thisdownward pressure of the upper part forces some.

of the cement outwardly and against the inner surface of the neck, sothat such cement which is thus forced out from between the stopper partswill serve when set to effectually, positively, and permanently securethe composite or two-part stopper in place. The cement between the twoparts when set prevents their separation.

In practice the two-part stopper is externally tapered toward its lowerend to correspond as near as possible with the interior shape of thebottle-neck; but notwithstanding the fact that there may beimperfections in the bottle the cement will firmly hold the stopper inplace.

It will be understood that before the two parts of the stopper arebrought together the valve 10 is introduced into the sleeve 6. hen thebottle 9 stands perpendicular, or substantially so, the spherical valve10 will rest automatically against its seat, so as to close the port 11against the ingress of fluid should the latter be simply poured into theupper part of the neck of the bottle. I have indicated hereinbefore thatthe valve 10 cannot be unseated by the use of wire or similar means.\Vhen the bottle is tipped to effect the discharge of l its contents,the valve 10 will roll away from i its seat, uncovering the port 11,whereby the l liquid can flow from the interior of the bottle, l throughthe port 11, into the tube 6, through the apertures 8 and 'ports 13, andinto the channel 12, from which the liquid flows into the neck and outof the end thereof.

It will be understood that the stopper can be located at any suitableposition within the neck and that its external shape may be of anydesired character.

Having thus described my invention, what I claim is- 1. A bottle-stopperincluding a sleeve externally reduced, a second sleeve having a closedtop and adapted to receive the externally-reduced portion of the firstsleeve and having a port, the first sleeve having a duct to registerwith said port, and a guard extending outwardly from the crown or top ofthe second sleeve and located directly over said port.

2. A bottle-stopper including a sleeve, externally reduced to form anannular shoulder along the bottom thereof and having diametricallyopposite apertures in its upper edge, and a second sleeve to receive thereduced portion of the first sleeve and externally reduced in its upperportion, said second sleeve havinga closed top provided with segmentalguards overhanging the externally-reduced portion thereof, and saidsecond sleeve having ing with said apertures.

3. A bottle-stopper including a sleeve, externally reduced to form anannular shoulder along the bottom thereof and having diametricallyopposite apertures in its upper edge, and a second sleeve to receive thereduced duced in its upper portion, said second sleeve having a closedtop provided with segmental guards overhanging the externally-reducedportion thereof, and said second sleeve having ports in the reducedportion thereof, registering with said apertures,combined withaspherical valve in the first sleeve and automatically closable againstthe port therein.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
